Rhode Island Journeyman Plumber Practice Exam

Urinals should not replace more than what percentage of water closets?

1. 50%

2. 100%

3. 120%

4. 150%

The correct answer is: 120%

Urinals traditionally serve as an alternative to water closets, designed to reduce water consumption and improve efficiency in commercial and public restrooms. The regulation indicates that urinals should not replace more than a specified percentage of water closets to ensure proper sanitation and convenience for users. The correct answer specifies a percentage that is based on plumbing codes and standards. Allowing urinals to replace up to 120% of water closets acknowledges that while urinals are a beneficial addition for water conservation, they cannot become the sole fixture relied upon in restroom facilities. This percentage is likely established to maintain a balance between the types of fixtures available, ensuring that there are adequate facilities for both male and female users in a restroom environment. In this context, maintaining a limit helps promote hygiene, comfort, and accessibility, especially in environments with high traffic, such as schools or commercial buildings. Having too many urinals could lead to insufficient toilets available for those who require them, thereby negating the benefits of including urinals in the first place.
